This is why I have been an advocate for Remote Play, and a future PlayStation and Xbox Phone. I am on the go a lot, and play via Remote Play all the time. Having the ability to pay for a game once, and have it available on Vita, PS4, and PS4 Pro is an incredible value.
That was also a huge selling point for me with the Switch. Being able to play Zelda and Mario on the TV, and on the go, with full console quality is exactly what I have always wanted from Nintendo. I am looking forward to Smash and Lets Go Pikachu this fall, because whether I am at home, or on the go, I will be able to play.
I have tried a couple 3rd party games on the Switch, but found that I can still get a better expereince via Remote Play on Vita and PSTV from my PS4 Pro. That said, it is great to have multiple options to access my Sony, Microsoft, Nintendo, and 3rd party games whenever and wherever I want.
Now, I just want Sony, Microsoft, or Nintendo to offer a connected Mobile gaming device with access to their library so I can have my games, and my phone all in one device again. Nov 2013 - Apr 2017 when I was using Vita as my Phone, and Remote Play to PS4, was the best years of gaming I have expereinced so far. Having the ability to play AAA Retro style games day and date with console via a single purchase, on a PlayStation, Xbox, or Switch Phone would be perfect colmination for classic style games.
Only thing that will top that is once VR reaches the point that is is possible on Mobile and Home.
Remote play is nice... If you are willing to sink in the cellphone fees required for that. Also not every place has decent cell or wifi coverage. I barely have enough latency for smash 3ds on campus.
For example, people in Australia would be screwed so hard...
